Characteristics

• Reduction of the thermal cooling of the heat generator
• Reduction of the cooling of the room through the flow-operated safety device for gas-fired furnaces without forced draught
• Improvement of the efficiency of furnaces at multiple boiler connection
• The flue gas damper prevents air from the boiler room to be extracted when the furnace is standing still
• Sound level reduction when more than one furnace are connected to one chimney
